PIN-SETTER.

.automatically set the pins placed therein when the lowering mechanism is released and after the pins are set the lowering mechanism will return to its upper receiving position.

A further object of the invention is to provide a pin setter which will automatically adjust itself to pin holding position when swung upwardly and which will securely hold the pins inserted therein until again lowered. I

A further object of the invention is to provide a pin setter which is of simple construction, is well adapted to withstand the hard usage to which it is ordinarily subjected and which may be manufactured at a minimum cost. I

With the above and other objects in view, the invention consists of the improved pin setter and its parts and combinations as set forth in the claims, and all equivalents thereof.

Specification of Letters Patent.

angular Referring to the drawings the numeral 10 indicates the vertical and 11 the horizontal portion of the frame or support to which the improved pin setter 12 is attached. This frame or support may be the ceiling and one of the side walls of a room or any other support desired may be used. The pin setter comprises a horizontal triangular pin frame member 13 formed of angle iron and is provided with two standards 14 extending upwardly from the opposite sides thereof to which are pivotally connected parallelogram arms 15 and 16. In vertical plane the arms on each side are parallel with relation to each other and their rear ends are pivoted to ears 1? projecting forwardly from the support 10. These arms with the standards and thesupport form a parallelogram connection between the triangular member and the support and provides for said member always remaining in a horizontal'plane while swinging from its setting position to its receiving position.v The upperarms 15 are extended forwardly and converge toward each other at the same angle as the triangular member and are connected together at their ends as indicated by the numeral 18.

Pairs of pin holding members 19 and 19 extending transversely across and beneath the triangular member are supported on straps 20 which are carried by the said tri member. These transverse pin holding members are laterally, slidably mounted upon the straps 20 and are pro vided with pairs of pin holders which are Patented Aug. 10, 1915.

shaped to conform to the contour of the ten- I tions 21 and 21 which are connected to the opposite edge portions of the pin holding members 19 and 19'. The opposite edge portions of the said members 19 and 19 are recessed as indicated by the numeral 23 to accommodate the curved portions 24 of the holders. When the two sections of each holder are positioned close together they form a circular holder open at both ends and of less diameter at its lower end than at its upper end and as the lower diameter is less than the medial diameter of the tenpin the tenpin will be held securely in the holder when in the position just described.

All of the pin holding members 19' are connected together by means of the longitudinal connecting strips 25 and the forward member is provided with forwardly projecting curved strips 26 which are pivotally connected to the three arm lever 2 carried by the triangular frame.v This three arm lever is pivotally mounted between the forwardly projecting portions 28 of the triangular frame and the strips 26 are connected to the arm lever at a point above its pivotal connection with the triangular frame by means of a connecting link 29. The holding members 19 are also all connected together by longitudinal strips 30 which at their forward ends are pivoted to the lower end of the three arm lever by a connecting link 31 so that when the three arm lever is moved in one direction the opposite movements of the strips will separate the holding members and permit the pins held thereby to be discharged and when moved in the other direction the holders will be in pin holding position. The longitudinal holder strips are held in proper position by means of the transverse strip 32 which is provided with depending fingers 33 positioned in pairs on opposite sides of the longitudinal strips. The transverse strip also serves to prevent the endwise movement of the holding members. In order 'to move the holding members quickly to open position when the setter has approximately reached its lowermost position a coiled spring 34 interposed between the horizontal arm 35 of the three arm lever and the triangular frame is provided which will actuate the said three arm lever to-separate the holding members and release the tenpins.

A spring retrieved bell crank dog 36 pivoted on the triangular frame is provlded with a shouldered portion 37 under which the outer end of the arm 35 snaps and is locked in pin-holding position. The arm 35 is released from engagement with the dog 36 by a releasing rod 38 having its lower end connected to the horizontal arm 39 of the bell crank dog and its upper end portion slidably connected 'to the parallelogram arms 15. A stop nut 40, adjustably threaded "on the rod 38, is adapted to be engaged by the arm 15 moving toward its lowermost position and swing the dog out of engagement with the three arm lever.

The holding members are moved to closed positions through their connection with the three arm lever by means of a closing rod 41 which is pivoted at its lower end to the outer end portion of the three arm lever and at its upper end has a slidable connection with theforward end of the parallelogram arms 15. This closing rod 41 has a nut 42 adjustably threaded on its upper end which is engaged by the said arms 15 in swinging to their upper position, and this engagever and the positions.

The pin setter is swung to its upper position by means of the rope 43 which is attached to the three arm lever 27 at its lower end and from this point the rope extends upwardly and over pulleys 44 and 45 and at its opposite depending end is provided with a counterweight 46. The counterweight while suflicient to pull up the. setter without the.

pins is overbalanced by'the weight of the pins when inserted in the setter. When the empty setter is swung to its upper position it is held by a spring latch 47 and controlled by a cordl48 extending to a convenient point of operation. I

The spring latch is provided with a holding recess 49 into which a pin 50 projectingarm lever bv the rope52 and at its other end is provided with a counterweight 53. The lever is pivoted to an upstanding frame or other support 54 and this support is provided with a spring dog 55 having a recessed portion 56 which is engaged by a pin 57 projecting from the side of the lever 51 in substantially the same, manner as the latch of the principal form described. A string 58 leading-to a convenient point is provided for tripping the dog.

In operation the setter swings to its upper position and is held by the recessed dog. In this position the holding members are closed and held locked by the bell crank dog engaging the three arm lever. Tenpins are now inserted in the pin holders and will be held thereby. The rope is now pulled to release the spring dog and the combined weight of the setter and the pins will overbalance the counterweight and the setter will swing downwardly. In swinging down wardly the distance between the triangular frame and the outer end portion of the up per parallelogram arm will decrease in length and when almost at their lowest points the upper arm will strike the nut of the releasing rod and release the three arm lever. and permit its spring to move the pin holders to open position. The setter is now relieved of the weight of the pins and the counterweight will swing the setter to its upper position and .in swinging to its upper position the forward end of the upper arm will engage the nut of the closing rod and swing the three arm lever to close the pin holders and the setter. is again in position to receive the pins and be again actuated in the'manner before described. I From the foregoing description it will be seen that the pin setter is of very simple frame in upper position, pin holding members slidably connected to said frame for releasably securing the pins therein, said pin frame adapted tobe swung to a lower position by the weight of the pins inserted therein, and means controlled by said sup porting means for operating said pin holding members when said frame reaches its lower position. i
